Definitions
- the invention is related to the technology of display, and more particularly, to a display module as well as the method of installation of the display module.
- LCD display constructions There are two types of LCD display constructions, i.e., cell and open cell during the manufacture process of a display module.
- cell liquid crystal is filled in the gap between two substrates and then the two substrates are sealed to form a module, whose appearance is the same as a normal piece of glass.
- connection ports are provided to a cell-based display module for external signal, i.e., open-cell.
- a backlight module is not included in the display module so made.
- a display module cannot illuminate by itself but through the backlight module.
- the backlight module is crucial in the display industry.
- the backlight module is composed of a light source, a light guide, an optical membrane, a rubber strip and a backboard.
- the illumination efficiency is dependent from the matrix arrangement between the backboard structure and the light source. Therefore, it is an issue to be solved in the design of backlight module to make it light-weight, thin, high luminosity and low cost.
- most of the backlight modules are integrally formed.
- a backlight module as shown in Fig.
- FIG. 1 has a liquid crystal plate 103, prism plates 104, 105, a diffusion plate 106, a reflection plate 107 and an LED board 108, all of which are sandwiched between a backboard 101 and a front frame 102.
- Side faces 1011 of the backboard 101 and side faces 1021 of the front frame 102 are sealingly combined such that the backboard 101 and the front frame 102 together form a sealed space.
- a rubber strip is provided to the side face 1011 of the backboard 101 and the side faces 1021 of the front frame 102 so that the liquid crystal plate 103, the prism plates 104, 105, the diffusion plate 106, the reflection plate 107 and the LED board 108 are firmly sandwiched between the front frame 102 and the backboard 101.
- Numerous light sources 1081 are mounted on top of the LED board 108, which allows light coming from the light sources 1081 to penetrate through the reflection plate 107, the diffusion plate 106, the prism plates 104, 105 as well as the liquid crystal plate 103 and eventually leave the front frame 102.
- the front frame 102 and the backboard 101 are made of metal to gain the best heat dissipation effect, however, dismantling the combination of the backboard 101 and the front frame 102 for maintenance and repair is difficult and troublesome when there is malfunction happened to one or some of the light sources 1081.
- US 2010/0172154 A1 discloses a display module with an installation frame.
- the primary objective of the embodiment(s) provided for the present invention is to overcome deficiencies in the current technology and provide a multi-function display module and the installation method of the same to solve the problem of high cost in the manufacture process.
- the display module manufactured includes multiple function plates and an installation frame.
- the installation frame is composed of multiple installation strips interactively connected together and provided with installation devices so that the function plates are installed inside the installation frame.
- installation strips for the installation frame saves the cost for integral backboard, front frame and rubber strips.
- the installation strips can be commonly used for all sizes. That is, no more production lines for different display sizes are needed, which greatly reduces manufacture cost and beneficial for the manufacturer to control the overall budget, let alone easy maneuver and strong adaption for display sizes.
- the installation frame is composed of four or more installation strips. Each free end of every one of the installation strips is interactively connected to one another to form the installation frame.
- the embodiment of the present invention includes a light board detachably mounted on the installation frame to facilitate dismantle for easy repair and/or maintenance.
- the light board includes a base which is made of a material efficient for heat dissipation.
- an installation recess defined in an inner face of the installation frame is provided for the function plate.
- the function plate at least includes a LCD display fitted by way of a pressing element to be secured inside an installation face formed on the installation frame.
- a heat dissipation device is provided to each of the installation strips.
- a method for installing a display module which includes the steps of:
- installation strips Connecting the installation strips to form the installation frame so that the function plate is able to be mounted inside the installation frame saves the material for, such as, the backboard as well as the front frame. Furthermore, because the only thing required is to cut the installation strips into segments of different sizes/lengths to fit the requirements of different display sizes, installation strips can be commonly used so that there is no need to design various molds to manufacture displays of different sizes, which helps reduce production cost, beneficial for manufacturers to control overall budget and easy adaption for requirements of size.
- the installation frame is composed of four or more installation strips. Each free end of every one of the installation strips is interactively connected to one another to form the installation frame.
- the embodiment of the present invention includes a light board detachably mounted on the installation frame to facilitate dismantle for easy repair and/or maintenance.
- the light board includes a base which is made of a material efficient for heat dissipation.
- an installation recess defined in an inner face of the installation frame is provided for the function plate.
- the function plate at least includes a LCD display fitted by way of a pressing element to be secured inside an installation face formed on the installation frame.
- a heat dissipation device is provided to each of the installation strips.
- Fig. 14 four sides marked with the letter B of the installation frame are defined as inner sides, four sides in contrast to inner sides and marked with the letter C are outer sides, an end marked with the letter D of the installation frame in connection with the LCD panel (open cell) is defined as the first end and an end marked with the letter E of the installation frame in connection with the light board is defined as the second end.
- the display module adopts the installation frame to fix, by way of installation devices, function plates inside the installation frame which is composed of multiple installation strips interactively connected together.
- the preferred embodiment of the present invention saves the material for the integrated metal backboard as well as front frame, which greatly reduces manufacture cost let alone the trouble for preparation of different molds for backboards of different sizes.
- the only thing, in the process of preparation for the installation frame, is to cut the installation strips into different lengths.
- the manufacturers are able to effectively control manufacture cost and the adaption for different sizes of the display module is thus readily solved.
- the detachably mounted light board on the second end of the installation frame is relatively convenient for repair and/or replacement as it only requires the dismantle of the light board on the second end of the installation frame and no need to dismantle the entire display module, which leaves the function plates, the LCD panel, the optical membrane as well as the diffusion plate on the first end of the installation frame intact from the maintenance to the light board on the second end of the installation frame.
- Heat dissipation devices mounted on the installation frame ensures the safety of the use of the display module.
- the display module constructed in accordance with a preferred embodiment of the present invention includes an installation frame 20 composed of multiple installation strips 201 interactively connected together and function plates 30 firmly mounted inside the installation frame 20 through installation devices 203, as shown in Fig. 3 which is an enlarged perspective view of a portion of the display module shown in Fig. 2 .
- Fig. 3 is an enlarged perspective view of a portion of the display module shown in Fig. 2 .
- the installation device 203 which is an elongated strip like element.
- the installation device 203 is bent to conform exterior appearance of the installation frame 20 so that when there is a curve or a right angle appeared on the installation frame 20, the installation device 203 can still satisfactorily combine the installation strips 201.
- Each of the installation strips 201 has a groove 2011 defined in an outside face of each of the installation strips 201 and having a depth adapted to a thickness of the installation device 203 such that after the installation devices 203 are respectively received in the grooves 2011 of the installation strips 201, the installation devices 203 do not protrude out of the grooves 2011, preferably, the top face of the installation devices 203 are flush with the top faces forming the grooves 2011.
- the installation device 203 includes an elongated bar with holes defined in two distal ends thereof and bolts intended to extend through the holes of the elongated bar.
- one distal end of the elongated bar is placed at a joint of two adjacent ends of two installation strips 201 and the bolts are threadingly extended through the holes of the elongated bar to secure the combination of the two installation strips 201.

- the installation frame 20 includes four installation strips 201 interactively connected together to form the installation frame 20 and two adjacent distal ends of two respective installation strips 201 are combined through the installation device 203.
- An installation groove 205 is integrally formed inside the installation frame 20 to secure the function plate 30 inside the installation frame 20 so that when the installation frame 20 is formed and the function plate 30 is about to be placed inside the installation frame 20, sides of the function plate 30 are able to be received in the installation groove 205 inside the installation frame 20.
- the function plate includes 30 at least a light board 302 and an LCD panel 304.
- an installation face 207 near the light board 302 is formed on the installation frame 20 to allow the light board 302 to be detachably mounted thereon for quick access for maintenance and/or replacement of the light board 302.
- the light board 302 includes a plurality of light units 303 detachably mounted on the installation face 207 of the installation frame 20.
- the light units 303 are detachably mounted on the installation frame 20 through bolts.
- Each one of the light units 303 has a flat side and a stepped side 3023 oppositely formed relative to the flat side.
- the flat side of one light unit 303 is placed under the stepped side 3023 of another light unit 303 with a gap defined therebetween for easy access for dismantle.
- the provision of the stepped side 3023 of the light unit 303 secures the combination of two adjacent light units 303 and also prevent light from the light units 303 from scattering out from the back of the light units 303 and, therefore, enhances luminosity of the light units 303.
- dismantle when repair and/or replacement is required for the light units 303, dismantle is limited to only the malfunctioned one(s) and a massive scale of disassembly of the light units 303 is not necessary.
- it is preferably unscrewing the bolts and then using the gap between the stepped side 3023 of one light unit 303 and the flat side of an adjacent light unit 303 to separate the two adjacent light units 303 such that the user is able to proceed repairmen and/or replacement.
- FIG. 9 a front plan view of the display module of the embodiment of the present invention is shown.
- the light board 302 includes a base 3022 and light sources 3021 mounted on the base 3022.
- the base 3022 is made of a heat dissipation material, such as, aluminum, to dissipate heat generated from the light sources 3021.

- the light board 302 has a base 3022 detachably mounted on the installation face 207 of the installation frame 20 and light sources 3021 arranged on top of the base 3022.
- the base 3022 is made of heat dissipation material so as to dissipate heat generated from the light sources 3021.
- the base 3022 is composed of multiple strip-like elements interconnected together.
- first and second installation grooves 208, 209 are integrally defined in the installation frame 20 for receiving therein the function frame.
- the function frame includes at least a LCD panel 304, a diffusion plate 306 and an optical membrane 308.
- the LCD panel 304 is inserted into the first installation groove 208 while the optical membrane 208 and the diffusion plate 306 are inserted into the second installation groove 209. Because the installation frame 20 is made of multiple installation strips 201, when the installation 20 is formed completely, the LCD panel 304, the optical membrane 308 and the diffusion plate 306 are properly and securely received in the first and second installation grooves 208, 209.
- Heat dissipation fins 2012 are formed on either an inner side or an outer side of the installation strips 201.
- a cover 50 is provided to prevent pointed edges of the heat dissipation fins 2012 from being damaged or hurting people.
- the cover 50 may be snap fit to sides of the heat dissipation fins 2012 or secured on the installation frame 20 by way of bolts.
- a second installation face 206 is formed on one side of the installation frame 20 for installation of the LCD panel 304.
- the LCD panel 304 is securely fixed on the installation face 206 through a fixing device 60.
- the fixing device 60 includes at least a pressing bar and bolts. After one side of the pressing bar securely abuts against one side of the LCD panel 304, bolt(s) are implemented to extend through the other side of the pressing bar and into the installation frame 20 to allow the LCD panel 304 to be securely fixed on the second installation face 206.
- the second installation face 206 and the second installation groove 209 are integrally formed on one side of each of the installation strips 201 and the installation face 207 is formed on the other side of each of the installation strips 201 for dismantling or installing the light board 302.
- the light board 302 is detachably mounted on the installation face 207, while the optical membrane 308 and the diffusion plate 306 are inserted into the second installation groove 209.
- the LCD panel 304 is fixed on the second installation face 206.
- the advantages provided by the embodiments of the present invention include: Adopting the installation strips to form the installation frame saves the integral metallic backboard and front frame.
- the installation strips can be cut into any length to adapt to different size requirements, which enhances the maneuverability of operation. Therefore, the overall cost for production is reduced and the manufacturer(s) is able to control the cost efficiently.
- the light board is detachably mounted on the installation frame so that maintenance and/or repair of the malfunctioned light sources on the light board is readily easy.
- the light board is composed of multiple strip like elements, which allows replacement to only the malfunctioned one(s) to be individually processed.
- the material used for making the light board is a heat dissipation material, which enhances the overall heat dissipation effect of the display module and protects the light source as well.
- Heat dissipation fins 2012 are formed on one side of each of the installation strips to thus prolong the lifespan of the display module constructed in accordance with the preferred embodiment of the present invention.
